Hi, I went through the creation process of ES sandbox, but I haven't received any mail about the created sandbox. But when I tried to repeat the creation the system said I have already an active sandbox. I tried to access the instance from the "Instances" page but it drops HTTP Error 504. I assume the creation process of sandbox wasn't completed (this is why I didn't receive email about the Sandbox).  Please help me: How can I get a working ES Sandbox? Thank you in advance!
